Both patterns aim to separate concerns and manage the flow of data between the UI and the underlying data models, but they do so in different ways. Let’s explore both patterns with […]

The wrapping happens using something called SuspendCoroutine. What is a SuspendCoroutine suspendCoroutine is a builder function that mainly used to convert callbacks into suspend functions. Let’s say for example you have some legacy (or not) Api, that uses callbacks. You can […]

In this post we will examine five Kotlin scoping functions (aka higher-order functions): apply, with, let, also, and run. When learning these five functions, you will need to memorize 2 things: how to use them, and when to […]

Because Room takes care of several concerns for you, e.g. caching, networking, Android highly recommend using Room instead of SQLite. If you are coming from iOS, the good news is that Room is very similar to the core […]
